Silicon carbide (SiC) MOSFETs are becoming popular in Permanent Magnet Synchronous Motor (PMSM) driver designs. The power dissipation of is an important reference for evaluating the efficiency PMSM drivers and implementing thermal design. This article performs loss analysis a three-phase, two-level based on SiC to evaluate driver's MOSFETs' temperature under rated operating conditions. transient switching process MOSFET clarified this paper, conduction losses calculated MOSFET's parameters....
Dual-three-phase permanent magnet synchronous motor (DTP-PMSM) with one open-circuit phase will suffer from reduced peak torque and increased output fluctuations due to direct current (DC) bus voltage limitation. The paper puts forward a DTP-PMSM fault-tolerant control strategy based on Quasi-Z-source inverter (QZSI) ensure that the electric drive system can deliver rated speed under one-phase-opening fault condition. First, utilization of DC dual-Y phase-shifted 30° PMSM is analyzed....
